DEVICE FOR ADJUSTING THE HEIGHT OF A FIRST PART RELATIVE TO A SECOND PART, A RETROFIT KIT FOR SUCH A DEVICE AND HEIGHT-ADJUSTABLE SYSTEM COMPRISING A PLURALITY OF SUCH DEVICES

摘要

A device for adjusting the height of a first part relative to a second part includes a first hollow profiled element, a second hollow profiled element which is displaceable along its longitudinal axis relative to the first hollow profiled element, a drive unit for displacement of the second hollow profiled element relative to the first hollow profiled element and a support unit which, in relation to the longitudinal axis, is arranged between the first hollow profiled element and the second hollow profiled element for the purpose of supporting the first hollow profiled element against the second hollow profiled element.
